After messaging with CuseNation.com, it was said that Curtis, a sophomore offensive tackle, had his account hacked when the news was announced.
However, Marrone acknowledged it was Curtis who tweeted out the news.
Marrone found out the news right before meetings earlier today. He apparently told Curtis they would meet later to discuss what course of action should be taken. In cases like this, Marrone said typically the parents are contacted first prior to an official annoucement.
He was informed of the tweet this afternoon. When he confronted Curtis, the sophomore offensive tackle acknowledged it was a mistake to tweet the news.
Here is what Marrone said during Wednesday's press conference.
"I found out this afternoon, late, we had meetings," he explained. "The doctors recommended that Kris, because of his medical issues, would not be able to play again. I literally tried to grab Kris. I said, 'Kris, listen, we're going to meetings and have a scrimmage. Let's make sure we get together tomorrow and talk about this.' The normal procedure is for a student-athlete is to call the parents before we announce anything.
"I was made aware when I was coming off the bus by my director of operations that Kris had tweeted that. I saw Kris just now and said, 'Kris why would you do that?' He said, 'I know I made a mistake. I should've come in and spoken with you first.'
"Those things happen with kids. And that's the situation."
